- Product Description
Potassium Formate Crystalline Powder – Premium Drilling & Industrial Grade Chemical Solution
SHANXI ZHAOYI CHEMICAL CO., LTD has been making formate and acetate chemicals for a long time. Our production history runs 36 years back to 1988. The plant covers 27,000 ㎡ and keeps a steady annual output of 150,000 tons. We ship Potassium Formate Crystalline Powder in two high-purity grades. One is industrial grade (≥96.0% purity). The other is premium grade (≥97.0% purity). ISO certification is in place, and KOSHER and HALAL approvals back it up too. The powder is white and hygroscopic. Solubility is strong, past 330g/100ml at 20°C. Heat stability reaches 210°C, and carbon steel shows no corrosion. Brine can be built with it at densities up to 1.57 SG. So it works widely in HPHT oilfield drilling, airport runway deicing, and industrial buffering systems. Costs stay low and performance stays reliable across many industrial jobs.

Key Features & Benefits
Built for harsh operating conditions, ourthis product clears the bottlenecks crews usually run into on site. Density control stays precise in HPHT well drilling. Barite sag never shows up. ECD management risk drops a lot, and downhole operation stays safe.
The formula does not corrode. Downhole tubulars last 40% longer than with conventional chloride-based chemicals. Mixing on site takes far less time because the product dissolves fast. In the field, that means 15-20% lower overall operating costs for clients.
Environmental compliance gets simpler too, for municipal work and for offshore work. Bromide and zinc-based compounds used to create messy waste disposal problems. Those problems are gone here. The product is fully biodegradable and it meets the North Sea PLONOR discharge rules. Store it the right way and its special hygroscopic structure keeps it working steadily, even when humidity levels shift.

How It Works
Potassium Formate Crystalline Powder dissolves fast in water. Potassium and formate ions are released, and the result is a clear brine with high density and no solids. Those ions tune wellbore osmotic pressure with real precision. Pressure stays stable through drilling and completion work.
Set it against potassium chloride and formate ions do a better job of dehydrating clay. Shale swelling falls by 30–50%, and the wellbore holds together better. Even at top density the brine keeps a steady yield point and low plastic viscosity. Circulation downhole stays smooth as a result.
For deicing, it brings water's freezing point down to -60°C. Concrete damage stays very low. Its strong buffering ability also neutralizes CO2 and H2S acid gas intrusion. That keeps downhole equipment intact through long-cycle well operations.
Applications
Oilfield Drilling: A good fit for particle-free drill-in fluids in HPHT reservoirs where bottom-hole temperatures go above 200°C. In open-hole completions it reaches over 90% return permeability. Formation damage stays low at the same time.
Completion & Workover Fluids: Works for deep well packer fluid and perforation pill jobs. Barite sag does not happen during static placement, so hydrostatic pressure control stays consistent.
Aviation Deicing: Airports use it a lot to keep runways clear of ice. Ice melts faster with it. Next to the old urea-based deicers, it also does less harm to the environment.
Industrial Processes: It often works as a synthetic catalyst when pharmaceuticals are made. Textile mills add it as a dyeing auxiliary. In leather tanning, it serves as a pH buffering agent.

Certifications & Compliance
Our plant holds ISO 9001:2015 quality management system certification. Each batch comes out the same as the one before it. KOSHER and HALAL certificates open the door to more uses, food-grade formulas among them.
The product fully meets OCNS Group E offshore environmental discharge standards. We implement strict heavy metal control standards (Arsenic <5 ppm, Mercury <1 ppm), with all indicators verified by quarterly ICP-OES third-party testing.

Packaging Options
Standard Package: comes in 25 kg multi-layer kraft bags. Each bag resists moisture and holds a polyethylene liner inside. For stable shipment, put 40 bags on every pallet (1,000 kg net). Shrink wrapping goes around each one.
Big-volume projects can order bulk. That means 1,000 kg giant bags with a moisture-barrier covering. Custom packaging is possible too. We can shape it around the distinct logistics needs you have.
Complete COA paperwork comes with each shipment. Every package also carries a label. On it you will find the batch number, the manufacture date, and a traceability QR code.

Manufacturing Process
Formic acid and potassium hydroxide are made in reactors where the temperature is tightly controlled, which gives a high-purity result. Air gets little chance to reach the product, because the whole crystallization step runs in a closed loop. Purity stays high from start to finish.
Trace impurities come out through centrifugation in several stages. Drying then runs at low humidity, with the settings tuned to the batch. That stops the powder from caking too early and keeps the crystal structure whole.
Every finished batch passes over 100-mesh sieves, so the particle size comes out even. Packaging is flushed with nitrogen by machine. Under normal storage conditions, that adds real shelf life.
